Chill out: Wolves take snow days too, says study

When snow falls, wolves chill out, according to a recent study from the University of Alberta.

Over two winters, researchers looked at the movements of grey wolves near Fort McMurray, Alta. in conjunction with data on snowfall in the area.

“We found that on the night that it was snowing, wolves rested more than they travelled, and when they travelled, they travelled slower than on other days when there wasn’t any snowfall,” Amanda Droghini, a former master’s student with the biology department. 

The researchers also found that within a day of the snowfall, the wolves returned to their normal movement behaviours. They don’t know exactly why the wolves changed their movements, but they have some theories.

“We think that it might be something about actively falling snow,” said Droghini.

Snow, like rain, clears the air of scent molecules, she said. Wolves rely heavily on their sense of smell to hunt, especially at night. Most of the wolves studied do their hunting after dark.

Another possible explanation, said Droghini, is that the wolves’ prey move less in falling snow.

“We unfortunately don’t have the data to test this,” she said, but if other animals are hunkered down, waiting for the snow to stop, there is no incentive for the wolves to go out hunting.

The researchers used data from remote cameras that monitored snowfalls, and collars on 17 wolves. These wolves were also part of a separate study that looked at the movement of wolves and moose near Fort McMurray.

It’s hard to say right now how climate change might affect the behaviour of wolves in snow, said Droghini.

Information about snow conditions is scarce, particularly in the North where there aren’t many weather stations.

Droghini said more freeze and thaw cycles could make movement difficult for animals in winter.

Rain after snow can create an icy crust over the snowpack, and this kind of snow is the most challenging for animals to walk through, she said.

“It costs them a lot of energy.”

The concern, said Droghini, is that it might be more difficult for animals to maintain the energy levels they need for the reproductive season.

OTTAWA — Major companies and government partners are lending their support to Carleton University’s newly established Women in Engineering and Information Technology Program.

The list of supporters includes Mississauga-based construction company EllisDon.

The latest to announce their support for the program also include BlackBerry QNX, CIRA (Canadian Internet Registration Authority), Ericsson, Nokia, Solace, Trend Micro, the Canadian Nuclear Safety Commission, CGI, Gastops, Leonardo DRS, Lockheed Martin Canada, Amdocs and Ross.

The program is officially set to launch this September.

It is being led by Carleton’s Faculty of Engineering and Design with the goal of establishing meaningful partnerships in support of women in STEM.  

The program will host events for women students to build relationships with industry and government partners, create mentorship opportunities, as well as establish a special fund to support allies at Carleton in meeting equity, diversity and inclusion goals.

VR tech to revolutionize commercial driver training

Serious Labs seems to have found a way from tragedy to triumph? The Edmonton-based firm designs and manufactures virtual reality simulators to standardize training programs for operators of heavy equipment such as aerial lifts, cranes, forklifts, and commercial trucks. These simulators enable operators to acquire and practice operational skills for the job safety and efficiency in a risk-free virtual environment so they can work more safely and efficiently.

The 2018 Humboldt bus catastrophe sent shock waves across the industry. The tragedy highlighted the need for standardized commercial driver training and testing. It also contributed to the acceleration of the federal government implementing a Mandatory Entry-Level Training (MELT) program for Class 1 & 2 drivers currently being adopted across Canada. MELT is a much more rigorous standard that promotes safety and in-depth practice for new drivers.

Enter Serious Labs. By proposing to harness the power of virtual reality (VR), Serious Labs has earned considerable funding to develop a VR commercial truck driving simulator.

The Government of Alberta has awarded $1 million, and Emissions Reduction Alberta (ERA) is contributing an additional $2 million for the simulator development. Commercial deployment is estimated to begin in 2024, with the simulator to be made available across Canada and the United States, and with the Alberta Motor Transport Association (AMTA) helping to provide simulator tests to certify that driver trainees have attained the appropriate standard. West Tech Report recently took the opportunity to chat with Serious Labs CEO, Jim Colvin, about the environmental and labour benefits of VR Driver Training, as well as the unique way that Colvin went from angel investor to CEO of the company.

While the world comes out of the initial stages of the pandemic, COVID-19 will be continue to be a threat for some time to come. Companies, such as Zen Graphene, are working on ways to detect the virus and its variants and are on the forefronts of technology.

Nanotechnology firm ZEN Graphene Solutions Ltd. (TSX-Venture:ZEN) (OTCPK:ZENYF), is working to develop technology to help detect the COVID-19 virus and its variants. The firm signed an exclusive agreement with McMaster University to be the global commercializing partner for a newly developed aptamer-based, SARS-CoV-2 rapid detection technology.

This patent-pending technology uses clinical samples from patients and was funded by the Canadian Institutes of Health Research. The test is considered extremely accurate, scalable, saliva-based, affordable, and provides results in under 10 minutes.

Shares were trading up over 5% to $3.07 in early afternoon trade.
